Diagnosis of Erectile Dysfunction (Impotence)

You will be asked about your symptoms and medical history. A physical exam will be done. Be prepared to identify every medication you are taking. As many as 25% of erectile dysfunction cases are due to medications. Expect questions about the frequency, quality, and duration of your erections. Your answers may help determine if primarily psychological and/or physiological factors are causing your impotence.

Your penis, testes, and rectum will be examined. If a physical cause is suspected, laboratory tests may be ordered. The following factors will be evaluated:

Nocturnal erections
—Potent men have spontaneous erections at night. If you do not remember them because you were asleep, there are devices that can measure and record them.

Psychology
—There are always psychological factors associated with sexual functioning, whether they are the cause or just a result. You and possibly your partner may be given a questionnaire to help determine what emotional and psychological factors may be contributing to your condition.

Cardiac function tests—These tests may be considered by your doctor. Poor cardiovascular function is associated with erectile dysfunction.
